The copies collide and undergo chemical reactions, producing new paired nucleotide sequences. A DNA sequencer decodes these sequences. Finally, a computer algorithm reconstructs the molecules ...

To date, people have encoded information into DNA the same way nature has, by linking the four nucleotide bases comprising DNA—A, T, C, and G—into a particular genetic sequence. Making these ...

Mutations are alterations to a DNA sequence. If one thinks of the information in DNA as a series of sentences, mutations are errors in spelling the words that make up those sentences. Sometimes ...

Today EMBL-Bank, the nucleotide sequence database of the European Molecular Biology Laboratory (EMBL), celebrates its 25th anniversary. It was the world’s earliest public database of DNA and RNA ...
